1. Upon receipt of the December 1958 Progress Report stating
the completion of phase I, we desire to establish our views relative
to initiating phase II. Since specific details cannot be established
until the final report is received and reviewed, this memorandun is
intended only as a guide in studying the report to achieve phase II.
2. It is our hope to accelerate this program toward production
by identifying phase II as prototype development rather than engineering
model development. With detailed layout guidance and the experience
gained by the contractor during the study phase, we feel that sub-
assembly configuration will produce the prototype.
3. Our plot/ming, therefore, will progress from the study report
to layout designs. The end result for production purposes will be
systems containing an antenna, filter, crystal holder, and universal
mounting brackets for a video amplifier and recorder. Due to the size
and shape of the low band antenna, all units for this assembly will be
board mounted except the antenna.
4. We recommend, therefore, that planning be started for two
complete prototype systems as follows:
-/AL. Fabric mounted logarithmic periodic antenna 50-500 mcs
with an equipment board containing a filter, crystal holder, and
space for ancillary equipment.
/16 Board mounted logarithmic periodic antenna 500-1000 mcs
also containing a filter, crystal holder, and space for ancillary
equipment.
C. Board mounted logarithmic periodic antenna 1000-10,000 mcs
also containing a filter, crystal holder, and space for ancillary
equipment.
-/
D. Horn antenna 10-40 kmc with a built-in crystal holder
mounted on an equipment board with space for ancillary equipment.
The bandpass filters for this system are expected to be dielectric
wafers.

5. We are anxious to accelerate this program because stocks
of currently used antennas are low and. delivery of replacements, on
order for fourteen months, remains indefinite. Fbr further discussions
